Fatigue is one of the most common complaints brought to doctors, friends, and relatives. You’d think in this era of labor-saving and convenient transportation that few people would have reason to be so tired. The causes of modern-day fatigue are diverse and only rarely related to excessive physical exertion. Today, physicians report, tiredness is more likely a consequence of underexercise than of wearing yourself down with overactivity.
Physical fatigue is the well-known result of overworking your muscles. (46) Physical fatigue is usually a pleasant tiredness, such as that which you might experience after playing a hard set of tennis, chopping wood, or climbing a mountain. The cure is simple and fast: You rest, giving your body a chance to get rid of accumulated waste and restore muscle fuel.
(47) Illness induced fatigue is a warning sign or consequence of some underlying physical disorder, perhaps the common cold or flu or something more serious like cancer, while other symptoms are present that often suggest the true cause. Even after an illness passed, you’re likely to feel dragged out for a week or more. (48) Take your fatigue as a signal to go slow while your body has a chance to recover fully even if all you had was a cold. Pushing yourself to resume full activity too soon will certainly prolong your period of fatigue.
Emotional problems and conflicts, especially depression and anxiety, are by far the most common causes of prolonged fatigue. When such feelings are not expressed openly, they often come out as physical symptoms, with fatigue as one of the most common manifestations. (49) Understanding the underlying emotional problem is the crucial first step toward curing psychological fatigue and by itself often results in considerable lessening of the tiredness. Professional psychological help or career or marriage counseling may be needed.
There is a great deal you can do on your own to deal with both severe prolonged fatigue and those periodic washed-out feelings. You might try to do moderate exercise. (50) Contrary to what you may think, exercise enhances, rather than drains, engery and helps you to resist fatigue by increasing your body’s ability to handle more of a workload. At the end of a day exercise can relieve accumulated tensions, give you more energy in the evening, and help you sleep more restfully.

参考答案：
身体上的劳累通常是一种令人愉快的疲惫，比如打一场激烈的网球、劈木柴或者爬山之后可能就会有这种感觉。
解析：
[要点分析] 此句应该注意代词that及其后的定语从句的翻译。根据语义可以得知代词that指代前半句中的表语a pleasant tiredness，而定语从句其实也就是对名词短语a pleasant tiredness的修饰。因此，在翻译时，有必要在后面用名词短语“这种感觉”部分地重复前面的名词短语“愉快的疲惫”。另外，定语从句中的主语you没有必要翻译出来，这里代词you泛指任何人，因为这种疲惫感是任何人都能体验到的。考查点：对代词的指代的判断和翻译。
